Biotopové nároky lejska malého (Ficedula parva) v lesích jižní a východní Moravy
Holek, Michal
This study investigates the habitat requirements of the Red-breasted Flycatcher at 41 sites in the Drahanská vrchovina, Chřiby, Hostýnsko-vsetínská hornatina and Bílé Karpaty based on the observed abundance of the species in the breeding season 2022. At the sites, the locations of its occurrence and the locations of checkpoints without the presence of the lei were recorded inside and outside the site. Stand characteristics were then collected at these points and then analysed for their statistical significance for the species' occurrence. Forty-seven Red-breasted Flycatchers were recorded at the study sites. Distance from water, forest development stage, amount of dead wood, distance from the edge of the stand and beech (Fagus sylvatica) cover had a significant effect on the occurrence of the Red-breasted Flycatcher. Distance from water emerged as the most significant characteristic, with 51 % of individuals found within 90 m of a watercourse. Red-breasted Flycatcher preferred emergent and, to a lesser extent, mature logs with significant amounts of dead wood. These were mainly stands with beech cover above 80 %. The Red-breasted Flycatcher was shown to be an interior-nesting species, as 85 % of individuals were found more than 100 m from the edge of the stand. The thesis concludes by discussing the findings and comparing them with the literature. From the results, recommendations for forest management are proposed for effective conservation of the Red-breasted Flycatcher in forest habitats.
